-
-We do require compare-and-swap (CAS), so we must instruct libatomic_ops
-to provide it, even if the architecture does not have instructions for
-it.
-
-For example, on ARM, LDREX is required for fast CAS. But LDREX is only

-anything below, like ARMv5. But ARMv5 is always UP, so using an

-slower).

-Tell libatomic_ops to provide CAS, even if the hardware is not capable
-of it, by using emulated CAS, as per libatomic_ops dosc:

-
- If this is included after defining AO_REQUIRE_CAS, then the package
- will make an attempt to emulate compare-and-swap in a way that (at
- least on Linux) should still be async-signal-safe.

+Subject: [PATCH] erts/ethread: instruct libatomic_ops we do require CAS
+
+We do require compare-and-swap (CAS), so we must instruct libatomic_ops
+to provide it, even if the architecture does not have instructions for
+it.
+
+For example, on ARM, LDREX is required for fast CAS. But LDREX is only
+available on ARMv6, so by default libatomic_ops will not have CAS for
+anything below, like ARMv5. But ARMv5 is always UP, so using an
+emulated CAS (that is signal-asyn-safe) is still possible (albeit much
+slower).
+
+Tell libatomic_ops to provide CAS, even if the hardware is not capable
+of it, by using emulated CAS, as per libatomic_ops dosc:
+ https://github.com/ivmai/libatomic_ops/blob/master/doc/README.txt#L28
+
+ If this is included after defining AO_REQUIRE_CAS, then the package
+ will make an attempt to emulate compare-and-swap in a way that (at
+ least on Linux) should still be async-signal-safe.
+
+Thanks go to Thomas for all this insight! :-)
+Thanks go to Frank for reporting the issue! :-)
